Provided is an air supply system capable of suppressing a reduction in the performance of an air dryer. The air supply system performs a supply operation of causing compressed air supplied from a compressor (4) to flow from upstream to downstream via an air dryer (11) having a filter (17) and a check valve (19). The air supply system is provided with an ECU (80) that switches between a supply operation for starting the supply operation under the condition that the detected air pressure is equal to or less than a supply start value, and a non-supply operation for not supplying compressed air to the upstream of the check valve (19), and performs a regeneration operation for regenerating the filter (17) in the non-supply operation. The ECU (80) is further provided with a non-supply continuation condition for not performing the supply operation as long as the regeneration operation is performed, despite the detected air pressure being equal to or less than the supply start value.
提供一种能够抑制空气干燥器的性能下降的空气供给系统。空气供给系统进行使从压缩机(4)供给的压缩空气经由具有过滤器(17)和单向阀(19)的空气干燥器(11)从上游流向下游的供给动作。空气供给系统具备ECU(80),ECU(80)对以检测空气压力在供给开始值以下为必要条件来使供给动作开始的供给动作、以及不向单向阀(19)的上流供给压缩空气的非供给动作进行切换,在非供给动作中进行使过滤器(17)再生的再生动作。ECU(80)还具备非供给持续条件,非供给持续条件用于尽管检测空气压力成为供给开始值以下但是只要在再生动作的中途就不进行供给动作。
